Topic of the practice

Energy efficiency in buildings

Good Practice Information

The objectives were to reduce the energy usage and increase the levels of comfort. The building was built in 1969 and no upgrade works had taken place since. The building is one of 27 libraries in Cork County and was the highest energy user with an EPI of 386kWh/m2 (256kWh/m2 would be typical). The project included an insulation and lighting upgrade:
The Attic Space was upgraded with 200mm of Rockwool insulation
The existing T8 luminares were replaced with T5 low energy fittings
This project was funded by the County’s own resources. The cost of the works undertaken was €3,716. The annual saving measured in the first year were €2,859 with a projected payback of 1.3 years. This represents an overall saving of 26%.this project will act as a showcase for other similar type buildings

Evidence of success

This practice is considered good as it is an excellent demonstration that low cost low technology measures can be undertaken in buildings and can lead to significant energy savings and short payback periods.
Previous EPI: 386kWh/m2
Target EPI: 256 kWh/m2
Current EPI: 198 kWh/m2
